Final answer:
To prevent infection in preop procedures, antibiotics, sterile gloves, and hand hygiene are all utilized to maintain a sterile environment and reduce patient risk.
Step-by-step explanation:
As part of the preoperative procedure to prevent infection, all of the following measures would be used: antibiotics to reduce the risk of hospital-acquired infections (HAI), sterile gloves to maintain a sterile field during medical procedures, and hand hygiene to minimize the transfer of microbes. Together, these measures work to prevent sepsis and other infections associated with surgical procedures. The historical evidence, such as the work of Joseph Lister, and current medical practices both support the use of these specific methods to prevent infection and promote patient safety.
